A laminotomy uses an arthroscopic approach to opening the spinal canal for laser spine surgery. With no need for general anesthesia laser spine surgery can be performed in an outpatient surgical setting.
A laminotomy is laser spine surgery that is used to relieve pressure off the nerve root exiting the spinal canal. With increased amount of space for the neural tissue the nerve is thus released from its painful compression.
Laser spine surgery using a laminotomy procedure can be used to remove the ligamentum flavum. Over time the ligamentum flavum can thicken and if it thickens too much it may compress the spinal cord, leading to spinal stenosis. When the ligamentum flavum is removed, more space is made available in the spinal canal thus releasing the affected nerve causing the pain from compression to be alleviated.
Laminotomy originates from the Latin words Lamina - The bony plate that covers the posterior arch of the vertebra) and otomy - Act of cutting or making incision.
A laminotomy procedure can correct the following conditions
- Spinal Stenosis
- Herniated Disc
- Arthritis in the spine
- Bone Spurs
- Pinched Nerve from nerve root compression
- Excessive scar tissue formation
- Bulging Disc
Laminotomy - The procedure
Once a local anesthesia has been administered, a small incision will be made in the patient. Through this incision a round Depuy tube is place. An opening to the spine is slowly enlarged by placing a series of tubes increasing in size over the first tube. Without cutting or tearing, the surrounding muscles are pushed out of the way allowing for minimal damage and a faster recuperation rate. The final tube to be inserted into the patient is about 18 millimeters in diameter, which is about as big as a small marker. A laser, camera, the suction and irrigation, along with other surgical instruments are inserted through this tube.
Once everything has been put into place, the surgeon can begin the laser spine surgery. As the nerve is freed or released from its compression, some patients will feel an immediate alleviation in their pain.
At the end of the laser spine surgery the tube is slowly removed. This allows for the muscles to move back into their natural position. The initial incision will sometimes require a stitch or two to close. The patient is monitored for one or two hours and then as long as they are accompanied by a patient, they are allowed to go.
During the afternoon or the evening after the patient’s procedure, they are encouraged to take a long walk. The following day the patient returns for a post-operative visit to get clearance from the doctor so that they can return home.
The advantages to a laminotomy
- There is no hospitalization as the procedure can be performed in a surgical outpatient setting
- Laser spine surgery does not require spinal fusion
- Highly successful
- No general anesthesia
- Patients will return to normal activities faster with shorter recuperation time
- Minimally invasive
- Minimal scar tissue formation
Laser spine surgery has many types of procedures that can help to alleviate back pain. The procedures range from laminotomy all the way through to spinal fusion alternatives.
